18 Small frame- 275cc high profile unders

Im 18 years old and from as young as i can remember ive always wanted breasts, I remember everyone telling me not to worry as puberty will sort it out unfortunately that wasn't the case, im still a 32A/ AA and very unhappy with my size, i have tried many things before surgery like going to a dietitian to try and gain weight hoping they would grow i have also spoken to my doctor to see if there were any alternatives but i soon found out to get my desired look surgery really is the only option. Im a slim build and 5'4 i also only way 7 stone 6, im hoping to bulk up abit before my surgery if anyone has any tips? Im hoping to go from a 32A to a full C or small D. I have my surgery booked for April the 13th 2017 and id like to document my journey on here.

I know that I'm definitely getting over the muscle implants but still very unsure what size CC to get, I currently wear a 32a though I barely fill it Id love to be a big C cup/ small D but don't want them to look too big as I have a small frame, would love to know what size people with a similar body type to me have had
